Analog Devices Inc./Maxim Integrated DS1284Q-T-R is a Real-Time Clock (RTC) IC featuring a parallel interface. This clock/calendar component provides 50 bytes of battery-backed SRAM for data storage. Key features include alarm functionality, leap year compensation, square wave output, and an integrated watchdog timer for enhanced system reliability. The device operates from a supply voltage range of 4.5V to 5.5V, with a separate backup battery input of 2.4V to 3.5V. Timekeeping current consumption is a maximum of 7mA at 5V. The DS1284Q-T-R presents time in HH:MM:SS:hh (12/24 hr) format and date in YY-MM-DD-dd format. It is supplied in a 28-PLCC (J-Lead) surface mount package on tape and reel. This component is utilized in applications requiring precise timekeeping and data retention, such as industrial control systems, data logging equipment, and embedded systems. The operating temperature range is 0°C to 70°C.
